Pneumatic drying device for straw mixture

Abstract

The invention discloses a pneumatic drying device for a straw mixture. The pneumatic drying device for the straw mixture comprises an outer drying barrel, an inner drying barrel which is connected into the outer drying barrel in a sleeving manner and is hermetically connected with the outer drying barrel, an upper drying cover body which is installed on an upper end part of the outer drying barrel and is openable, and a drying base which is installed on a lower end part of the outer drying barrel and is hermetically connected with the outer drying barrel, wherein a spacing interlayer between an outer sidewall of the inner drying barrel and an inner sidewall of the outer drying barrel is a ventilation channel; a plurality of second air holes communicating the ventilation channel with an inner cavity of the inner drying barrel are arranged in a wall part of the inner drying barrel; a drying air inlet tube communicating with an inner cavity of the drying base is arranged on a wall part of the drying base; and the inner cavity of the drying base communicates with the ventilation channel.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of energy, in particular to a system for producing biomass fuel by utilizing plant stalks. Background technique [0002] In recent years, crop straw has become a new source of rural non-point source pollution. Every year during summer harvest and autumn and winter, a large amount of wheat, corn and other stalks are always burned in the fields, producing a lot of thick smoke, which not only becomes the bottleneck of rural environmental protection, but even becomes the chief culprit that affects the urban environment. According to relevant statistics, my country, as a large agricultural country, can produce more than 700 million tons of straw every year, which becomes "waste" that is "not very useful" but must be disposed of. In this case, it is completely handled by the farmers, and a large number of burnings have occurred. Contents of the invention [0003] The purpose of the present i...
